Cun-CHALKING DEVICE.

To a-lliiwhom it. vIna-'y concern:

Be it known that I, Fonnns'r R. MAGUIRE, a citizen of the United Statesof America, residing at 'New Florence, in the county of YVestniorelandand State of Iennsylvania, have linvented certain new and usefulImprovements in Cue-Chalking Devices, of which the following-is aspecification, reference being had therein to the accompanying drawing.

This invention relates to a cue chalking device, and relatesparticularly to that class of devices employed for holding a piece ofchalk in a convenient position to permit of the cue tip bein lr placedagainst the chalk and the cue manipulated so as to apply the chalk tothe tip, and the invention has forits object to improve the constructionof such devices generally and rovide a chalkiiig device which may beattac ied to the leg of a billiard or pool table in such a manner thatit will be out of the way of tlie players and at the saine jtinie willbe in convenient position for use when desired.

The invention has for its further object to cue chalking device thatwill be simple construction, strong, durable, effective in itsoperation, and comparatively inexpensive to manufacture.

In the drawings: Figure 1 is an elevation of my device as applied to aleg of the billiard table, Fig. 2 is a cross sectional view of thesaine, Fig. 3 is a sectional vier: of a portion of the saineillustrating a roller bearing, Fig. 4 is a cross sectional view of thesame taken on the line x-x of Fig. 3, and Fig. 5 is a sectional view ofa portion of the chalking device illustrating a cylindrical chalkholder.

To put my invention into practice, I pi'ovide a tube or cylinder 1provided intermediate its ends, and closer to its outer end than toitsinner end, witla securing plate 3 by means of. which the tribe orcylinderis secured to a suitable support such as billiard table leg 4 asherein shown- -The tube or "tcylinder 1 extends at an aciieangle to thelate 3, in order that the chaiking device may e presented to the playerin the most convenient\manner for chalkins: the cue. The

touter end of the tube or ci. iinder 1 is provided withansintegralcoilar which has an annular groove lfpr a purpose as will presentlyappear. 'Dhesportion of the tube or cylinder 1 extending beyond thefront face of the securing plate 3 is materially shorter speciacationorLetters Patent. y

y' v n than that portion of the tubeior cylinder 1\ which projectsbeyond the rear face of said\ securing ,late 3, the su )port 4 beingvided wit i an opening 4 in which the said ortion of the tube orcylinder 1 .projecting eyond the rear face of the plate 3 is neatlyitted, thus providing a prolonged bearing for supporting the chalkingdevice, and relieving Patented sept. 15, laos.

the securing plate 3 of considerable strain Y that would be otherwiseplaced thereon.

A plunger rod 5 is received in the outer end of the tube or cylinder 1for reci rocatory movement in the said tube or cyliiii er 1, and

during such reciprocatory movement is adapted to be partially rotated bymeans' of a roller 7 which engages in a sinuous roove 6 foi-ined in therod 5 between the en( s of the latter. The roller 7 is mounted on atransversely extending pin S, and besides acting to impart artia rotarymovement to the lunger rot 5 during the reciprocation of the atter, alsoserves as the means for limiting both the outward and inward movement,or in other words, the longitudinal reci )rocation of the plunver rod 5.The said piunger rod 5 is provided adjacent its outer end with aninteriorly grooved collar 9, and, on its outer end, carries a chalkholding cup 10. This chalk holding cup may be of any form desired, andwhere the same is made cylindrical in form, screws 13 are employed forsecuring the chalk 11 against independent rotation in the cup. Thesescrews 11 also serve as means for securing to the cup an end cap 12,provided with a flaring mouth 1.4

which acts as a guide for centering the tip of the cue on the chalk 11.

The plunger rod is normally held in the extended position, aiid isreturned to its nornial position after cach actuation thereof, by meansof a coil spring 15, surrounding the rod 5, with its inner end receivedin the annular groove oi' scat 1 iovided therefor in the outer end ofthe cylinder or tube 1, and its outer end received in the annular grooveiii the collar 9. ency on the part of the plunger rod.5 twisting thespring 15, I refcrably provide antifriction balls 15a in t ie annulargroove in collar 9, the outer end of the s ring 15 seating against saidanti-friction ba s.

By roviding an extended bearing iii the reai' o the securing plate ofthe chalking device, I ani enabled to so mount the device on a billiardor like table as seen in Figs. 1 and .100 'y In order to relieve anytenddevice is presented t-o the player in the most convenient positionfor the effective chalking of the cue. l

While I have specifically described the preferred embodiment of myinvention, it will be obvious that various changes may be made in thedetails of construction without departing from the scope or spirit ofthe in- Vention claimed. f

Having now described my invention what 20 In a cue chalking device, atube or cylinder provided intermediate its ends with a secur *emo*plate, the greater portion of said tube or cylinder pro1ectmg beyond therear face of vert-ical line, the mouth 14 of t-he ehalking said plate:ind the outer end of the tube'or cylinder having an annular groove, :1lunger rod extending into said cylinder antFprovided adjacent its outerend with a collar having an annularlgroove, said plunger rod providedintermediate its ends with a sinuous groove, a roller mounted in thecylinder :md received in, said groove, a spring surrounding the plungerrod having its ends seated respectively in the groove in the outer endof the cylinder and in the groove in the collar on said rod, a. chalkholding eu earried by the. outer end of said plunger rot and a capsecured to said cup and'provided with a flaring guide mouthconnnunicating with the chalk holding cup.

In testimony whereof I afiix my signature in the presence of twowitnesses.
